Specificationof Letters Patent. Patented Sept. 30, 1913.

Application filed August 3,- 1912. Serial No. 713.110.

T 0 all whom it may concern:

Be it known that I, EARL xn'u'rxog a citizen of the United States, residing at Duluth. in the county ofSt. Louis ancl.State of Minnesota, have invented certaini new and useful Improvement-s irnShelf- "Boxes, of which the following is a specification. 1

My invention relates in general to shelf boxes,'a nd more particularly to boxes of.

this type which are designed to contain heavy articles such as hardware and the like,

although it will be apparent that the invention has a much wider application, being capable of efficient embodimentin shelf boxes of various types and numerous other A receptacles constructed for variouspurposes.

One of the principal objects of my invention is to provide a shelf box which while I "in time become loosened and displaced, and

" also without the use 0f glue or other adhe'sive which may be affected by the temperature and moisture of the air.

" As'till further object of the invention is to provide a shelf. box wherein thedanger of shrinkage and expansion of the walls forming the same will be reduced to a minimum. v v I Further objects and advantages of my invention will be apparent as it is better understood from the following description 'which, taken in connection with the accompanying drawing, discloses one preferred embodiment-)thereof.

On the drawing: Figure 1 1s a perspective "view oflaqshelf box made in pursuance of my invention; Fig. 2 is a plan view of the same; Fig. 3 1s a vertical sectional view taken on the line 3-3 of Fig. 2 showing the means of. securing the walls of the box together, and Fig. 4: isa transversevertical sectional-view taken on the line 4 of Fig. 2..

In the embodiment ofmy invention shown on the. drawing and hereinafter described,

' the shelf box is formed primarily of two mend members '10 and 11 of wood or other HENRY BEK- suitable material and a sheet of suitable metallic material 12 which forms the intermediate walls connecting the end'wall s. Each of the end walls 10 andll is provided with a transversely disposed slot-'or groove 13 formed in each outer vertical end face thereof. The metallic sheet 12 is bent substantially ,atright angles to itself along two parallel longitudinally extending lines 1 to form the bottom wall 14 and the sidewalls 15 and 16. The material at the end e es of the bottom wall is cut away a substantial distance to provide outwardly extending edges at each end of the verticalside walls; These edges are bent inwardly of the side .walls asat 17 and folded back upon themselves to provide folds 18 which are adapted to be inserted in their corresponding slots 13 formed in the vertical edges of the end walls. After the folds 18 have been disposed in the slots or grooves 13a pin 19 is driven downwardly within each fold. Itis frequently advisable to provide an en largement 20 at the base of the slot as is shown in Fig. 3 by boring a small round hole in the end wall to slightly greater depth than the length of the pin 19. the rest of the slot being formed by making a saw cut in the edge of the end wall communicating with the round hole formed as described. It is apparent that where the ends are made of softmaterial that the circular hole may be omitted and the pins used not only to expand the metal of the fold but also the material of the ends about the folds as the folds are expanded.

In Fig. 3 a comparatively short'pin is shown. as believe the box is given greater strength by its use than were'a longer one employed. as the material of the end wall beneath the end of the short pin aids in preventing the fold from sliding longitudinally in the groove.

tending-t0 withdraw the bottom portions of the folds' from the grooves or slots 13. The sheet 12 forming the walls 14, 15 and 16 is further held in position by bending inwardly its upper edges 22' over the'toos of This pin extends bea tween and expands only a portion of the E hardware stores.

the endwalls and '11. L'hese edges are preferably folded back upon themselves as at 23 before they are bent down to engage 'the tops of the end walls to prevent buckling of the sidewalls and to provide smooth rigid upper edges on the side walls of sulficient strength and evenness to permit the,

however, that this member mav be omitted and one of the articles contained in the box secured in its place, as is the custom in many One of the metallic sides 16 is provided with a depressed area 26 which is preferably covered with enamel upon which marks settin forth the cost, selling price and other information may be'made and readily changed without injuring the enamel.

,It will. be apparent that various changes may be'made inthe form, construction and arrangement of parts without departing from the spirit and scope of my invention, or sacrificing any of its advantages, the form hereinbefore disclosed being merely one preferred embodiment thereof.

I claim ILA shelf box having side and end walls, one of said walls having a transversely extending grooveat its end and a wall adjacent the said end having its edge folded upon itself and disposed in the said groove, and means fomspreading the said fold after the edge is in: position within the groove to secure the walls together.
